Comment:
There are a lot of other doctest failures caused by this package than the
ones fixed above. It is possible that some are spurious because I missed
something in the tickets listed above, but I will post them here for now.
Ones not covered elsewhere I describe.
sage -t "devel/sage/sage/calculus/calculus.py"
sage -t "devel/sage/sage/calculus/desolvers.py"
sage -t "devel/sage/sage/calculus/functional.py"
sage -t "devel/sage/sage/calculus/functions.py"
sage -t "devel/sage/sage/functions/log.py"
sage -t "devel/sage/sage/calculus/tests.py"
All of these are just order switches and should be trivial to fix.
sage -t "devel/sage/sage/calculus/wester.py"

Both of these have a problem with QQbar(e^(pi*I/3)). This is definitely
an algebraic number, so hopefully it's covered elsewhere. Specifically,
{{{
ges/sage/symbolic/expression_conversions.pyc in composition(self, ex,
operator)
729 if rat_arg == 0:
730 # here we will either try and simplify, or return
--> 731 raise ValueError, "Unable to represent as an
algebraic number."
732 real = operand.real()
733 if real:
ValueError: Unable to represent as an algebraic number.

sage -t "devel/sage/sage/symbolic/relation.py"
This is:
{{{
